Add io.0.2.0 and nproc.0.5.1

[rizo]

My first submission to the repository! :) Not sure what should happen next, though.

[camelus]

✅ All lint checks passed 9abc5e1

• These packages passed lint tests: io.0.2.0, nproc.0.5.1

---

✅ Installability check (4167 → 4169)

• new installable packages (2): io.0.2.0 nproc.0.5.1

Build scripts where missing in iter, added them now.

[avsm]

thanks for the fix -- have you pushed it though?

[rizo]

The problem was in one of the packages, so yes, I already updated it.

[avsm]

Still seems to be a build problem with a missing setup.ml -- need to run oasis setup?

[rizo]

Sorry, should be working now. Did a clean install to test.

[Chris00]

Should end with .git for opam to know it is a Git repository.

[rizo]

@Chris00, @avsm Thank you for your suggestions. I will update the oasis metadata definitions of all the packages and generate the corresponding opam files.

I have a question though: is there a way to install development packages? I know for local packages repo pinning can be used, but is there a way to force the latest master installation of a given package like in brew install ... --HEAD?

[rizo]

Another question: what is to be done when the package requires a library that cannot be installed with the operating system package managers? The ocaml-glfw requires libglfw3 but it's not present in apt repositories.

[Chris00]

You probably want to create a conf-libglfw3 that checks whether it exists on the system and, if not, either gives instructions to download it or downloads it and issue the proper commands to install in ~/.opam/<switch>/lib/stublibs/.

[Chris00]

Split $CAML_LD_LIBRARY_PATH for the later dir.

It's usually better to submit each package in a separate PR as it easier to identify individual errors. In that case iter and nproc seem to work fine.

For the external source not available in the old ubuntu distro, a somewhat hackish solution is to use the "source" depext: see

opam-repository/packages/orocksdb/orocksdb.0.2.1/opam

Line 25 in 0b9967e

[["source" "linux"] ["https://gist.githubusercontent.com/domsj/9a28ba5a523a3420ded8/raw/dc6ebd8768a87dee285e84438dc733dfc58e037f/gistfile1.txt"]]

for instance. This is not pretty it works (at least for testing purposes)

[samoht]

ping?

[rizo]

Thanks for the ping @samoht, and sorry for the late reply!

Unfortunately currently I don't have time to add and test external dependency installation for ocaml-nanovg and ocaml-glfw. I think I'll remove them for now and add other libraries which already pass the validation.

Also I decided to rename iter to flow (https://github.com/rizo/flow) to reflect a wider domain of the library. But then I realised there already exists a package by @smondet with the same name (https://github.com/smondet/flow/), which seems to be deprecated.

I guess I'll have to come up with a new name and then finish this PR.

[rizo]

I think everything's ready for review at this point.
